Coleopterol., 11(2): 135 - 170. An annotated list of 16 Lathrobium (s.str.) species is provided, including the two new taxa: L. (s.str.) generosum sp.n. from the NE Irkutsk Area and L. (s.str.) ishiharai ursinum ssp.n. from the NE Amur Area; L. (s.str.) viduum Eppelsheim, 1893 is redescribed, its aedeagus and female terminalia are illustrated for the first time; L. (s. str.) japonicum kunashiriense Y.Watanabe, 2004 is placed in the synonymy of L. (s. str.) japonicum Bernhauer, 1907. New faunistic data on Siberian and Far Eastern localities are given for all the species listed. Some short additional data are provided also for other territories of the former USSR.

I believe that a thorough Lathrobium (s.str.) species in these spacious study of both external morphology of species territories. Both my own field material and and structure of aedeagus, especially its internal numerous specimens received by me from other parts, as well as female genital segments, is collectors named below underlay the present necessary for the further development of the study. The vast collection of Dr. A.V.Shavrin classification. As well, I find some species groups (Daugavpils, Latvia) is to be mentioned specially; to require a substantial taxonomic revision and in part it has been identified and published by preparation of the revisions has been initiated Dr. Shavrin himself before, but unfortunately with by me recently. some errors and omissions I try to correct herein. An annotated list of the Lathrobium (s.str.) It is to be noted that there is no comprehensive species is provided below, excluding the classification of Lathrobium (s.str.).
